Be it known that I, CHARLES A. STURTE- VANT, a citizen of the United States, residing at Plainfield, in the county of Union and State of New Jersey, have invented new and useful Im rovements in Side Registers for Sheet-Fol ing and other Machines, of which the-following is a specification.

This invention relates to a side register for sheet-folding, rinting, ruling, and other Inachines in whic the sheets require to be registered at the side preparatory to being operated upon. v 1

The object of this invention is to'produce a register for t sheets to be more accurately registered at the side than has been possible heretofore, which .can be more readily adjusted fordifferent sizes or thicknesses of sheets, and which is superior in its detail construction. v In theaccompanying drawings, consisting of two sheets, Figure 1 is a fragmentary sectional elevation of a sheet-folding machine provided with my improved side-registering mechanism. Fig. 2 is a topfplan view of the same. Fig. 3 is a fragmentary longitudinal section, on an dnlarged scale, in line 3 3, Fig. 2. Figs. 4, 5, and 6 are horizontal sections in lines 4 4, 5 5, and 6 6, Fig. 3. Figs. 7, 8, and 9 are vertical transverse sections 1n lines 7 7, 8 8, and 9 9, Fig. 3, respectively.

Similar letters of reference indicate corresponding arts throughoutthe several views. The fol in -machine shownin' the drawings y improved side register pair of horizontal folding-rollers B B, tapes C, passing around a receivin -roll er D andcarrying the sheets over the oldin -rollers, and a folding-blade E, whereby the s eets are fed fr'om the tapes between the folding-rollers.

When the sheet comes to rest after being carried by the tapes over the folding-rollers the foldingblade,the same is registered at the side by In improved side-registering mechanism, whic is constructed as follows:

'F F represent the upper and lower jaws of the side-registering gripper. These jaws are arranged lengthwlse along the side of the path of the sheet to be registered and folded, so that. the sheet as it is carried forwardly by the tapes passes with its side edge between his purpose which enables the actuating-rod g,

of a main frame A, a"

the jaws of the gripper. The lower jaw consists of a ri id or inelastic plate having a beveled edge For directing or guidin the sheet over the same. The under side 0 this jaw is provided with a pair of sleeves G G, which are mounted, respectively, on an actuatingrod 9 and aguide-rod g. These rods are arranged horizontally and parallel in the vmachine below thecarrying portions of the tapes and are supported at their-inner and outer ends in brackets H H on the main frame. The guide-rod g is fixed on the brackets H H, but the actuating-rod g is movable thereon. The lower. gripper-jaw is frictionally connected with the guide-rod 9, so that the same and the parts connected therewith are held in position while the gri per-operating mechanism opens and closes t e jaws. This frictional connection. is formed by dividing the sleeve G, sothat the up er part is integral, with the lower jaw, whi e the separable ower part G is loosely connected with the upper part by a screwt', loosely'connecting said parts on one side of the rodg, a screw '5, connected with one part of the sleeve G and passing loosely through the other part o'nthe opposite side of the guide-rod g, and a spring t surrounding the screw i and operating to draw the parts of said sleeve yieldingly a ainst opposite sides of the guide-rod g. The other sleeve G is mounted loosely on the so that the latter can slide freely through the same, while the lower gri per-j aw is held frictionallyon the guiderod against movement with the actuatingro j The upper gripper-jaw consists of an upwardly-taperin .block of rubber or other elastic materia and is secured at its upper end in a correspondingly-shaped socket .or opening 7', formed in the upper arm of an elbow-shaped gripper or rock lever J. This lever is pivoted on the rear part of the lower jaw by a horizontal screw or pin is, so as to turn in a vertical plane, and its upper arm, which carries the upper flexible gripper-jaw, projects horizontally forward over the fixed jaw, while its lower arm projects downward in rear of the lower jaw, as shown in Fig. 3.

-At the rear or outer end of the lower gripper-jaw the same is rovided with an upwardlyprojecting wali or standard L, which has a vertical slot 1, through which the upper which is pivotally connected 0 chill in the top end-of the rear slide-section and a collar 0 3 arm of the gri per-lever projects.

The rocking movement of the gripper-lever ds N N, which are mounted on the guide-rod and actuatingrod in rear of the grl per. Each of these slides has a complete s eeve .n, which is mounted loosely on the guide-rod, and a split sleeve n, the parts of which are clamped against oppositesides of the actuating-rod by a screw, '12 as shown in Figs. 8 and 9. The front slide N is rovided on its front side-with a lug 0,

two sections or cross-hea arm of the gripper-lever J. The two sections of the slide are adjustably connected by a horizontalscrew 0, which has its screwthreadedfront endworking in a threaded whi e its rear part turns in the rear slidesection, but is compelled to move lengthwise therewith. The preferred construction of this connection (shown in the drawings) con. sists in. seating the screw in upwardly-opening recesses 0 formed in lugs 0 on the upper makes @oherotation for every s eet that is fed to the machine andis so timed thatthe actuating-rod is moved forward to the end of its stroke after the sheet has been fed between the jaws of the grip er, then moves backward to the end of t e stroke in this direcregistered is em ing the lower jaw.

In this positionof the gr'pper-lever its lower arm'bears at its front s1 e against the rear end of the lower gri per-jaw, this arm being referahl'y provi ed with a bearing face or ug s for engagjaws the gripper- After the sheet has been fed between the aws of the 'pper the actuating-rod moves forward to t e end of itsstroke in this direcslide composed of.

During this forward movement of.the gri er theqregiste'rin face Z Pg g thereof is engage with the side edge of the sheet to be registered. During the first part of the subsequent backward movement of the actuating-rod g the gri er does not move with the same, but is hel fiictionally in place on the ide-rod g. While the gripper is thus he d stationary the slide-section N,

which is pivotally connected with the-gripperlever and continues to move backwardly with the actuating-rodcausesthis lever to turn and move the upper gripper-jaw downwardly toward the lower jaw, thereby griping the heet between them, as shown in igs. 3 and 7. After the sheet has been thus grip ed between the upper andlower jaws the atte'r, together with theshe'et held thereby, are moved laterally with the actuating rod to the end of the backward stroke of this rod. When the gri per reaches this osition, the sheet is proper y re istered. T e lower gripper-jaw 1s nowheld rict-ionally at rest on y the guide-rod 9 during the first part of the following ing-rod, and during'this time the-gripperele- -v'er is turned for lifting the upper .jaw from forward movement of the actuatthe lower jaw, thereby releasing the sheet.

After the gripper same remains stationaryuntil the registered sheet has been carried away to the folding mechanism or other devices and the next sheet to be registered is fed between the griphas been thus opened theper-jaws, when the registering operating is repeated.

In side-registering gri pers as heretofore constructed the gripper would not begin its lateraLmovement with-the sheet until the upper fleirible jaw was compressed against the sheet on the lowerjaw sufficiently to overcome the friction between the lower gripper-'aw and the guide-rod. "The be in= rung of t is movement therefore de ende on the elasticity of the upper jaw, an since this. elasticity is iable to var z'the point at which the gripper comes to res u on being moved lateral varies 'correspon' ingly and produo'es inaccurate registering in the same measure. In order to avoid this, the rocking movement of the lever J in the direction for closing the jaws is arrested positively and the elastic up er jaw is constructed to engage the sheet lying upon the lower jaw in advance of this arrest and then-yield unfil-tlieclosing movement of the rock-lever is positively arrested. The sto foe-thus arresting the closing movement 0 theripper-lev'er consists, preferably, rear end or ed e of the'lo'w'er jaw and at the lower end of he slot in the standard, as shown in Figs. 3, ,5, and 7.

For the purpose of adjustin the gripper to different widths of sheets the bolts or screws n are first loosened,-after which the slidesections and the gripper-jaws are moved lengthwise of the guide and actuating-rods approximately into the desired osition and then the clamping-screw n of t e slide-sec-' tion N is tightened for securing the same to the actuating rod, thereby effecting a coarse The adjustingscrew 0 is now turned in the proper direction for moving the front slide-section Nrelatively to the rear section N until the fine or accue rate adjustment of the gripper has been produced, after which the clampin -screw n of the front slide-section is also tightened for. securing the latter'on the actuating-rod. The

side-registering device is now ready for use. T- represents a curved .or inclined guideplate 'or guard whereby "the; sheets while moving forward with the carrying-tapes are directed underneath the upper aw of the grip er. This guide-plate is arranged above the ower jaw and providedwith a rearwardlyopenin recess t, through which the upper arm 0 he ipper-lever moves. purpose of a different thickness or quality the same is adjusted vertically by the following means: I The rear side of the guide-plate bears against the vertical front face Z. of the wall L and isprovided with a uide-lug t, which fits into the vertical slot Zt ereof.

The pre erred means of effecting the connection between the vertical adjustin -screw and the wall consists in engaging t e screw with a later ally-o ening recess w in a cross-bar to at the top 0 the wall L and providing the screwgage-surface Z of the gri gripper may For the apting this guide to paper of as shownin Fig. 4;
